  2. Went after my stock turbine housing and manifold again. After getting awesome results by porting the manifold and turbine at work with an air powered grinder, and decking the mating surfaces almost 2mm each at the machine shop I decided to port the wastegate hole and deck the manifold 2 more mm. Here is my original porting...5k plus miles on this on a 12a and 14b. Not gong on a 14g do5h (so bigger exhaust and intake wheel) Almost 3 inch...on the manifold and turbine inlet and turbine outlet. Also used larger studs on the manifold to ensure perfect clamping force because al that porting made the gasket area thin. http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_manifold3inch.jpg http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_2013-04-20162432.jpg http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_2013-04-20162451.jpg decking... http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_SAM_2867.jpg For my next phase I just did more of the same.... For the manifold quick resmoothing of the casting marks. Pretty much to the point of it looking like tubing. Eliminates hot spots and stress risers. http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140627_193821.jpg And matching the manifold to turbine ports with a mirror.. http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140612_175426.jpg http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140627_180205.jpg http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140612_173819.jpg And deck the manifold all the way to that fat casting mark on the #2 runner http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140627_193714.jpg Next went after the wastegate hole.The flapper is 37mm , so I went with a 1 inch or just under 26 mm porting. I used a step drill to start a nice centered hole and finished with carbide burr bits. Grind here to allow the flapper arm to be pulled outta the way. http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140627_183846.jpg This lets you tape or otherwise secure the flapper outta harms way. I used a Tim's turbo business card. Seemed fitting since he gave me a line about how the arm has to be cut to port the wastegate. Liar. http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140609_102233.jpg O.D. AT 37mm http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140627_190255.jpg See the 1 inch bit clears the flapper, but grinding the chamber lets it get outta the way a little more. And increase the internal volume of the chamber so it can flow a little more maybe... http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140608_184706.jpg Bit is a little long... http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140608_184720.jpg Fix that by breaking off the tip...and finishing port with bits... http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140608_192744.jpg Used these bits and a drill and harbor freight die grinder work awesome! http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140627_190206.jpg The inverted flare bit worked good for smoothing the wastgate entrance... http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140627_183259.jpg Before porting... http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140608_191249.jpg After... http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140627_183228.jpg Finished by smoothing the contacts with some sandpaper.. http://i1187.photobucket.com/albums/z388/starionkiller/12a%20ported%20tourbo/th_20140627_184230.jpg The concept with the original porting and decking and grinding the heck outta the manifold was to allow more flow with all the porting for better high end power and better spool, the decking was to put the turbine wheel closer to the exhaust valve and to decrease the internal volume of the manifold so the engine exhaust could fill it quicker and thereby get the turbo moving quicker. Grinding off all the casting marks and heat shield mounts was to lighten it and reduce thermal mass and hot spots. Also make it look like a header especially when wrapped. The wastegate porting is to reduce boost spikes and allow a little better boost control. Its "experimental" right now because it can maybe allow exhaust pressure to push the wastegate open now that it has a larger surface. We will see what happens. I don't think I will be pushing it hard enough for that to happen though. Also the pressure on either side of the flapper will not be of such a difference with a 3 inch exhaust and all this porting. Overall I think it will help keep turbo speed consistent much like a fast acting blow off valve.
